platform/x86: silead depends on I2C being built-in

The new driver cannot be a loadable module, so if I2C is loadable, we get this
link error:

drivers/platform/built-in.o: In function `silead_ts_dmi_init':
silead_dmi.c:(.init.text+0x2ef): undefined reference to `i2c_bus_type'

This makes the Kconfig dependency stricter to require I2C=y.
